To all whom it may concern:

Be it known that HENRY S. VROOMAN, deceased, late of Boston, in the county of Suffolk and State of Massachusetts, did invent a new and useful Improvement in Sole-Channeling VMachine, of which the following is a specification:

The invention consists in the improvement of machines for channeling the soles of boots and shoes, as hereinafter described and pointed out in the'claim. l

In the accompanying drawing, Figure lis a sectional side elevation on the line w a: of

Fig. 3. Fig. 2 is a vertical section of Fig. 3. taken on the line y y. Fig. 3 is a'sectional shape maybe channeled on the same pattern;

but a number of patterns are employed for the various sizes and shapes of soles, all made in `the same manner and operated by the same means. The edge of the pattern is a cogged rack, D, which gears with the small spur-wheels EE, as seen in Fig. 3. This rack is held in gear by means of a roll, F, which bears against its inside. The roll revolves on a pin in the slide G, which is forced up by the spiral spring H on the shaft I. (See Fig. 2.) The wheels E E are revolved by means of the bevel-gears J and crank and shaft K K. For the removal of the pattern the roll and slide are forced back by means of the lever L. M is a movable arm which projects over the bed, and is connected with a Vertical post, N, which turns in the edge of the bed and the supportinglug O, so as to move the arm laterally. The

post and arm areheld` in position by the` Q. This roller bears upon the sole and keeps g it down Iirm on the pattern.FAttached to the back of the movable arm M, by means of a hinge, is the adjustable guide V, which is forced outward from the arm `by a spiral spring, as seen in Fig. 5. Theposition of this guide is regulated by the thumb-nut W.

"The guide bears against the edge of the sole as the pattern is revolved. The "arm M, with this guide attached, is made to swing ylaterally by meanslof the lever X, which is fastened to the post N.

A cord, which passes over a pulley,is at Vtached to this lever, and is connected to a treadle, so that by the pressure of the foot the arm is swung back for the removal ofthe pattern and placing the sole.

Yrepresents the knife or channeler, back of which is the groover Z, which is adjustably attached to the end of the lever Q. The knife and groover partake of the movement of the roll'er U, and are raised and lowered by means of the camlever S.

To operate with the machine, press down on the lever S, which lifts the knife and groover and roll U. Then, by pressing with the foot on the treadle, the arm M is swung back, or to one side. Now, place the sole on the pattern and release the treadle, which allows the guide V to press the sole. Then lift the lever S, which throws down the roll and knife, and by turning thecrank the sole is revolved, and the` channeling is completed.

The top of the pattern is cross-serrated, with spurs therein to hold the sole. When the sole is placed on the pattern, the operztchine, of the swinging arm M, lever Q, roll tion of channeling it is but the Work of a mo- U, pattern D, and bed A, as and for the purment, two or'three turns of the crank only bepose described. ing sufficient.
